A slang term for a man who is more sexually attracted to other men than to women. It is not usually derogatory but it can be sometimes. It has the connotation of a gentleman who is educated and refined and who does not "broadcast" their orientation.

"I don't think Chris wants to have sex with you Lauren - he's sly."
"I was totally plastered and I wanted to have sex with this really really hot guy, but it turned out he's sly, so he just walked me back to my dorm instead."
"I can never make friends with guys unless they're sly. Otherwise they are always staring at my breasts."

so like when I'm imagining "sly" I just see a real slick looking dude just posted up against a suspicious building under a shadow.. zoom in and the fucker has a tooth pick in his mouth just so effortlessly sweet

A guy I think that is cool and especially funny. He tries to put his grades up and tries to listen to the teacher when explaining a lesson. He sometimes draws but I don't think they're that good. Sometimes he's drawings are random, like sometimes he draws something cool and awesome and sometimes he just draws nonsense.

Sly tries to be cool around his friends and makes you laugh all the time.Sly cares what grade he gets and tries to recite in class. He tries to be quiet in his seat and tries to be obidient.
